Cheese & Asparagus Frittata

材料

• 1 small sweet onion
• 4 大 eggs
• 1/2 杯（小さじ） salt
• 2 杯（小さじ） olive oil
• 1 cup shredded low fat Swiss cheese
• 1 ポンド asparagus

調理方法

1. Snap the tough ends off of the asparagus and diagonally cut the spears into 1" lengths. Cut the onion into thin slices.
2. Heat olive oil in a 10" oven-proof frying pan over medium-high heat. Add onions and salt and cook, stirring occasionally, until onions are softened, about 3 minutes.
3. Add asparagus, reduce heat to medium-low, and cook, covered, until asparagus is barely tender, 6 to 8 minutes.
4. Lightly beat and add the eggs; cook until almost set, but still runny on top, about 2 minutes; pre-heat the broiler while the eggs cook.
5. Sprinkle cheese over eggs and place the pan in the oven; broil until the cheese is melted and lightly browned - 3 to 4 minutes.
6. Remove from oven and slide the frittata onto a serving plate.
7. Cut into wedges and serve immediately.
